Four-wheel drive grass grasping machine with wheel-side reducers

Abstract

The invention discloses a four-wheel drive grass grasping machine with wheel-side reducers. Each wheel-side reducer comprises a hub, a planetary gear carrier, a wheel-side support shaft, an inner gear ring and a sun wheel. Each wheel-side support shaft is sleeved on a corresponding half shaft. One end of each wheel-side support shaft is fixedly connected with a corresponding half shaft housing, the other end of each wheel-side support shaft is connected with a spline of the corresponding inner gear ring, and each gear ring and the corresponding wheel-side support shaft are fastened through a wheel-side support shaft nut. Each hub is supported through a bearing by the outer circles of the corresponding inner gear ring and the corresponding wheel-side support shaft. One end of each hub is fixedly connected with the corresponding planetary gear carrier. A planetary gear shaft is arranged on each planetary gear frame. A planetary gear is connected to each planetary gear shaft in a rotating way, and is meshed with inner teeth of the corresponding inner gear ring and outer teeth of the corresponding sun wheel respectively. Each sun wheel is connected with a spline of the corresponding half shaft. The wheel-side reducers are arranged in hubs of wheels, so that loads of a primary main reducer, the half shafts and a differential are reduced, the structure size of a transmission part is reduced, a rear axle is ensured to have a sufficient ground clearance, and the passage capacity of the grass grasping machine is improved; and shaft heads of the half shafts are thicker, so that the half shafts are difficult to break, and the overall equipment mass of the grass grasping machine is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a wheel-side reducer four-wheel drive grass catcher. Background technique [0002] At present, most of the grass grabbers are driven by the gearbox through the universal joint shaft to drive the drive axle, and the drive axle drives the single-stage final reducer of the road wheels. Poor, the shaft head is thin, the half shaft is easy to break, and the equipment quality of the whole machine is large. Contents of the invention [0003] The purpose of the present invention is to address the shortcomings of the above-mentioned prior art, and to provide a four-wheel-drive grass-grasping wheel-side reducer with a smaller axle package, better passing performance, thicker shaft head, and less likely to break the half-shaft. machine. [0004] Technical scheme of the present invention is realized in the following manner: [0005] Wheel reducer four-wheel drive grass ...
